ABSTRACT
Sweet potato, Ipomoea batatas (L.) Lam (Convolvulaceae), is an essential crop for food security in developing countries. Euscepes postfasciatus (Fairmaire) (Coleoptera Curculionidae) is one of the main pests of I. batatas in tropical and subtropical regions. It feeds on the tuberous roots of I. batatas and induces perforations tunnel-shaped with excrement. The objective of this study was to register, for the first time, the occurrence of E. postfasciatus in I. batatas in the municipality of Diamantina, Minas Gerais, Brazil. Individuals of E. postfasciatus were found in the larval, pupal and adult stages feeding on the roots, in the genotypes, Brasilândia Branca, Rubisol, UFVJM01, UFVJM02, UFVJM03, UFVJM04, UFVJM08, UFVJM18, UFVJM91, UFVJM291 and UFVJM526 in a greenhouse at the Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM). Euscepes postfasciatus injuries formed superficial and deep galleries with the presence of excrement and unpleasant odor. The record of E. postfasciatus in I. batatas in the municipality of Diamantina is important to develop local strategies for integrated pest management of the crop in the region.(AU)
